7 Claims. 1

The present invention relates to extractors and more particularly to a centrifugal extractor for packages of yarn.

During the operation of dyeing yarn packages of the type where the yarn is wound upon a mandrel tube, the packages become so distorted as to cause the ends of the package to bulge to such an extent that the yarn goes over the end of the mandrel tube. When packages so bulged are mounted on a creel for winding into warp or other form, the exposed end yarn becomes chafed and damaged.

Some of the objects of the present invention are: to provide an improved extractor for packages of yarn; to provide an apparatus for extracting liquid simultaneously from a number of packages of yarn; to provide a centrifugal extractor for yarn packages wherein provision is made for reshaping such packages as have bulged or de formed during the dyeing operation; to provide means for maintaining a pressure transverse to the applied centrifugal force in an extractor so that the ends of the packages are flattened; and to provide other improvements as will hereinafter appear.

In the accompanying drawings, Fig. l represents a plan of a yarn package extractor embody- .ing one form of the present invention; Fig. 2 represents, on an enlarged scale, a section on line 2-2 of Fig. 1; Fig. 3 represents a section on line 33 of Fig. 2; Fig. 4 represents a section on line 44 of Fig. 2; Fig. 5 represents a perspective of one of the yarn package receptacles, all of which are alike; and Fig. 6 represents a detail in plan of the cover control mechanism.

Referring to the drawings, one form of the present invention is shown wherein yarn packages it are respectively contained in receptacles ll, of which, in the present instance, there are ten fixedly mounted upon a rotatable plate I2 and arranged circumferentially about the axis of the plate and, preferably, radially equidistant from such axis. The yarn packages H! are each of well-known form wound about a tube which is generally of the perforated type. Since all of the receptacles H and associated parts are alike, the present description will be limited to one receptacle and its novel parts, since this is sufficient for a complete understanding of the invention.

A receptacle i I therefore comprises a cylindrical open top member rising from a bottom [3 through which an axially disposed package supporting spindle I l rises to a height sufficient to pass through the package tube and project as a guide for the tubular stem I5 of a perforated cover H5. The spindle It is bolted as shown at I! to the plate l2, while the bottom of the receptacle I0 is spaced from the plate [2 by a spacer l8 and anchored by a stud 20. This spacing allows the receptacle ill to drain through holes 2! provided in the bottom l3. That arcuate portion of the receptacle ill on the opposite side of the spindle I4 from the axis of rotation of the plate i2 is provided with perforations 22 covering the area juxtaposed to the adjacent side of a package in the receptacle. It should be noted that an annular bushing 23 is located in the hole in the bottom through which the spindle l4 passes in order to provide a clearance 24 of a size to receive the projecting end of the tube upon which the yarn is wound. Also, the tubular stem i5 is of enlarged diameter at its junction with the cover E6 to pro vide an annular clearance 25 about the spindle M to receive the other projecting end of the package tube.

In order to reshape the ends of the yarn package due to bulging during the dyeing operation, the cover I8 is provided and its stem l5 has telescopic relation with the spindle l4, permitting free relative sliding movement of the cover It under pressure applied to the projecting end of the stem l5 during the extracting operation.

In order to create this package reshaping pressure and also to prevent the cover from rising due to upward pressure of possible yarn expansion before the machine comes up to its extracting speed, two wing-like offset extensions 28 are welded or otherwise made fast in spaced relation to the side of the stem l5, and also preferably to the cover IE to provide a support for two pivots 2'i and 28. The pivot 28 transmits the motion of a centrifugally actuated arm at to the cover 16 to cause the latter to bear upon the end of a package to reshape any end malformation resulting from the dyeing operation. The arm 30 is pivoted at 3! between two upstanding angle plates 32, bolted or otherwise fastened to the rotatable table top 29, and receives its motion from a weight 33 fixed to the arm 36 in such spaced relation from the pivot 3| as to cause the cover It to move downwardly under outward swing of the weight due to centrifugal action. i

In order to prevent upward movement of the cover 16 due to pressure developed internally of the receptacle l l, two latch levers 34' are pivoted upon the pivot 28 being spaced apart to straddle the arm 30 with suitable spacing washers 35 interposed as shown. The free ends of the levers 34 are interconnected by a hand grip 36 for move.- ment together. Each lever 34 is provided with an arcuate faced stop 31 arranged in the path of a complemental faced short arm 38 of a latch bell crank 40. The two bell cranks 40 are pivoted upon the pivot 21, with the long arm thereof pivoted upon a pivot 4i passing through the plates 32. Thus, the two latch 'bell cranks straddle the two plates 32 at one end and at the other end lie between the two wing extensions 25, the arrangement being such that the respective short arms 38 are respectively in the plane of the two stops 37. Thus, when the cover I6 is lowered into contact with the top of a yarn package, the dual latch lever 34 is swungtola position parallel to the top of the stem I5 and is so located by means of a pin 42 transversely disposed between the two parts of the lever 34 and which meets the top of the wing extensions 26 as a limit. When so positioned, any upward thrust of the cover 16 is transmitted to the latch bell cranks 40 which are now in abutting relation to the stops 3'! and lock the parts against movement.

The plate or disc l2 upon which the receptacles ll are mounted is part of a central hub 44 which also supports the upper table 29, to which the latch and centrifugal assembly is mounted. Also, the table 29 is apertured circumferentially to snugly fit about the upper end portions of the respective receptacles. The hub it forms an extension of the main driven shaft (not shown of the machine and receives motion from a suitable source of power.

In order to facilitate the removal of the packages from the respective spindles I4, each spindle is provided with a flat or groove 53 at its upper end which serves to permit the insertion of a wire or the like which can be hooked into a perforation of the package tube and thus allow the package to be lifted out.

In operation, one yarn package is' placed in each of the receptacles l I and then the covers i 6 are respectively placed over the packages with each spindle end within the tubular stem i5 of the cover. The several latch levers 34 are now brought forward and down to engage the end of the stems IS in order to prevent the packages from shifting upward when the machine is started and thereafter to exert a downward pressure upon the covers 56 caused by the weights 33 swinging outward under centrifugal force. Since the weights 33 are above the respective pivots 3!, this swinging action will *be translated into a linear motion pressing the covers l6 against the packages with the desired squeezing action which restores any bulges or irregularities and results in flattening both ends of the packages while allowing the yarn mandrels to project a short distance from each end. This linear or straight line motion is made possible by the length of the bell cranks 49 and the location of the connections of the bell cranks 48 with respect to the pivots 21.
